Trains Held Short

Weekly average number of trains holding per day from the Surface Transportation Board's (STB) Rail Service Metrics. Data is broken out by train type (intermodal, grain unit, coal unit, automotive unit, crude oil unit, ethanol unit, other unit, and manifest) and by cause (crew, locomotive power, or other). To arrive at these figures, railroads are instructed to run a daily same-time snapshot and then calculate the weekly averages.

Querying over HTTP

Splitgraph serves as an HTTP API that lets you run SQL queries directly on this data to power Web applications. For example:

curl https://data.splitgraph.com/sql/query/ddn \
    -H "Content-Type: application/json" \
    -d@-<<EOF
{"sql": "
    SELECT *
    FROM \"internal-agtransport-usda-gov/trains-held-short-iacs-9uck\".\"trains_held_short\"
    LIMIT 100 
"}
EOF
